Sen. Kay Hagan, D-N.C., continues to staff her re-election campaign by bringing on two new aides: John Coady will serve as her finance director and Erika Brees will serve as her state finance director.

Brees and Coady are veterans of another targeted incumbent's re-election race: Sen. Claire McCaskill's campaign in Missouri last year. Coady held the same title with the McCaskill campaign, while Brees was her Missouri deputy finance director.

The junior senator from North Carolina is one of the most vulnerable incumbents in the 2014 cycle, although her GOP opponent is unclear. In the meantime, Hagan continues to bring on operatives for her re-election. She announced last week that she had hired Preston Elliott to be her 2014 campaign manager.
